Collect all the assorted image URLs from e2e tests in one place

utils/image/manifest has an additional `arch` parameter, which determines
whether an image ends in `-$ARCH` (like `-amd64`).

All locations that previously had gcr.io urls referenced in costants or inline
have been updated to refere test/utils/image.
